[The extraintestinal manifestations of Crohn's disease: our experience]

During a period of sixteen years we have treated 120 patients with Crohn's disease, 41 of them with extraintestinal lesions besides of it's main intestinal pathology. These patients represented the 34.1% of all attended in this service. We describe the clinical and epidemiological aspects and the incidence of extraintestinal manifestations of the disease. Joint manifestations were prominent (90.2%), followed by cutaneous-mucosal lesions (47.8%) and cholelithiasis (24.3%). Urinary symptoms secondary to fistula or invasion from the adjoining inflammatory process came in fourth place. Other rare localizations are described. The literature is reviewed.
